COMPLIANCE STATEMENT
This certificate of compliance lists the building features and specifications needed to comply with Title 24, Parts 1 and 6 of the California Code of
Regulations, and the administrative regulations to implement them.This certificate has been signed by the individual with overall design responsibility.
The undersigned recognizes that compliance using duct design, duct sealing, verification of refrigerant charge and TXVs, insulation installation quality,
and building envelope sealing require installer testing and certification and field verification by an approved HERS rater.

Special Features and Modeling Assumptions
The local enforcement agency should pay special attention to the items specified in this checklist. These items require special
written justification and documentation, and special verification to be used with the performance approach. The local enforcement
agency determines the adequacy of the justification, and may reject a building or design that otherwise complies based on the
adequacy of the special justification and documentation submitted. I Plan Field
The DHW System "Lennox HM61-175P-1"is a Larqe Gas water heater with Pilot Loss = 0 btuh.
HERS Required Verification
Items in this section require field testing and/or verification by a certified home energy rater under the supervision of a CEC-
approved HERS provider using CEC approved testing and/or verification methods and must be reported on the CF4R pian Field
installation certificate.
The HVAC System "HVAC' incorporates HERS verified Duct Leakage. Target leakage is calculated and documented on the CF4R.
The HVAC System "HVAC' incorporates a HERS verified Refrigerant Charge test or a HERS verified,Thermostatic Expansion Valve.
